AUTOMBJILE RIM AND WHEEL.'

Application lled January 31, 1920. Serial No. 355,416.

To all whom t may camera.'

Be it known that we, Josnrrr A. Roer and JOSEPH Z. 'll`oNDUL'r,l bothsubjects of the @King of Great Britain, residing at Edmonton, Provinceof Alberta, Canada, have invented certain new -and useful improvementsin Automobile Rims and Wheels; and we do hereby declare that the'following is a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

The present invention relates to automobile rims and wheels and moreparticularly l5 .to the rims of same.

rlhe principal object of this invention is to provide an automobilewheel rim so designed andconstructed as to afford the quicker chan ingof tires thereon.

s With the aV ove and other objects in vlew which may appear asinherently 'l related 1 with the scope and nature of the lnvention,l Alreference is now to be had to the hereunto annexed drawings wherein thedil'erent parts being designated byfynumeral characters throughout theseveral views are identied in this description by similar and corresending numeral characters.

5f the above mentioned drawings: Figure 1 is a cross-section of anautomobile wheel through the valve,

Figure 2 is a longitudinal section of part of said wheel through thevalve; and, Figure 3 is a cross-section of the rims and 4wheel away fromsaid valve.

In view of fully disclosing the invention, reference is now to be hadmore particularly to the above drawings which are collaterally relatedwith this description.

of the wheel 2 in the usual way, has its surface formed with threadswhich are suili- The iron rim 1, secured to the wood elly socket isscrew threaded' internally, so as to permlt the screwin 4in of tube 5. vl Rim 3 is threade on its under surface to ,screw on to run 1, and, ispierced by a hole 'with a tube nut 7 formed on the up er surface Saidhole and nut are screw t readed' internally to permit the screwing in ottube 5.. v l

Tube 5 .is a steel tube `which is screw threaded at one end externallyso as to screw into rims 1 and 3. The other end of tube 5 is screw thredinternally so as to 'recelve the valve cover 8, and, 1s formed with anut shaped end 5 so as to allow' for screwing and unscrewing when rim 3is required to be changed.

Tube 5 passes through the wood elly 2 of the wheel, screws into socket 6and rim l, then into rim 3 and nut 7 which it holds and firmly retainsin position, thereby making it impossible for rim 3 to move either way.

Tube nut 7 has a collar 9 let into its upper surface which is piercedwith a screw threaded hole for screwing on to the valve 10 of the airtube which it holds in position in the centre of tube 5.

As the valve from the air tube'lO cannot project beyond the underside ofrim 3, it is extended with a tube 11, which screws on to the valve-aftertube 5 has been screwed into position, and, is of sullcient length toextend beyond the wood ielly 2 of thel wheel, so as to allow connectionof the air pump, and is screw threaded externally at one end so as tovalve, an internally at the other end so as tol-)provide for theconnection with the air tu e.

0n the inside of the air tube is a solid rubber washer 12 which isadapted for the purpose of supportin the valve tube 10 and facilitatingthe sorewln on of tube 11.

The cover of the va Ve 8, which is there used to protect said valveagainst dust, is screw threaded externally so as to engage the threadprovided on the nut end of tube 5.

l In the drawings above referred to has been shown a sim le andpreferred forni of thel invention. that no limitation is necessarilymade to the precise structural details therein exhibited, but the rightis hereby reserved to any rovide for the connection of the' t is,however, ,understoodl changes, alterations or modifications to whichrecourse may be `had that come within the scope of the following claimsWithout departing from thel spirit of the invention or sacrificing theeiiiciency of the same.

Having thus fully described our invention, what We claim as new anddesire to secure by Letters Patent is 1. A demountable rim constructioncomprising in combination a folly having a rim therefor, a tire rim, athreaded connection between said rims, said rims having openings thereinadapted to extend in alignment when said rims are connected together, anexternally threaded tube'adapted to extend Within said openings forpreventing relative movement of said rims, and a tire valve extensionadapted to project throughv said tube beyond the felly substantially asandV for the purpose specled.

2. An automobile rim construction com- -prising in combination a fellyhaving a rim therefor a tire rim surrounding sald felly rim and havinginterlocking engagement therewith, said rims having openin s thereinadapted to extend in alignment W en said rims are connected together, anexternally threaded tube adapted to extend within said openin forpreventing relative movement ot sai rims, and a tire valve extensionadapted to' project through said tube beyond the felly substantiallyasand for the purpose specified.
